To? all: whom it may; concern? Ber. it known that I, Annoto GUUDEMAN'N, at citizen: ofthe United of New 'Jersey,:have invented certain newand: useful Improvements in Hand lhread ingi. Shuttles-M of which the following is a specification.

The: principal. object of this invention istoprovide a shuttle ofthe so-c alled' hand= threadingtype which shall be free- :of the slit-forming tongue or the like, now com+ mon'ly-employed in effecting the introduction of the thread to the thread-guiding eyelet corporate. a. tension means in a removable structure forming a part of the hand-thread ing means.

In the accompanying drawing, Figure 1 is a plan view of the improved shuttle; Fig. 2 is a side elevation of that end-portion of the shuttle to which the subject of the present invention relates; Fig. 3 is a similar view, showing the shuttle partly in section on the line 10, w of Fig. 1 or w, w of Fig. 6; Fig. 4 is a sectional view on the line w-m of Fig. 2; Fig. 5 is a sectional view on the line yy of Fig. 2; Fig. 6 is a sectional view on the line az of Fig. l; and, Fig. 7 shows a removable part of the shuttle removed and in side elevation.

at is the shuttle-body having the shuttle cavity 21 for the filling a and the means cl for supporting the filling. An extension 6 of this cavity extends toward one end of the shuttle and is formed with the opposed grooves or ways 6 (Fig. 6). Fitted into the side wall of the shuttle-body a and affording communication between the extension 6 of the cavity and the exterior is a filling-guiding eyelet f of usual form except that'it has an upwardly opening slit Referring to Figs. 1 and 3 to 7, h is a metallic plate which occupies the extension 6 of the cavity, standing in a vertical plane at that side of the cavity which adjoins the eyelet f. This plate has two angularly disposed walls i i projecting therefrom, each wall having a prO ecting toe j and the plate having an oppositely projecting rib is, the said toes and rib being adapted to enter the Specificationof Letters Patent.

Secured to' the wall 2" 811138 9 95 once it is It will be observed that the tongue ppro jec ts away from the supply of filling and past the thread eyelet f.- Through the side wallof the shuttle occupied by the filling eyelet f and back of the same relatively to the free end of the tongue ;0 an aperture t is formed, the same communicating with the slit 9 of the eyelet f by the angular slit a formed in said side wall of the shuttle. In the walls 2' z" is arranged a screw pin 0 on which is fulcrumed a tension plate w normally held flatwise against the plate It by a spiral spring w coiled about the pin '0 and having one end engaging the tension plate and the other secured to the pin. The filling is normally held pressed between the tension plate andthe plate It, being thereby kept under tension. By adjusting the pin 1) the degree of tension may be varied as will be obvious. Once the plate 72, has been introduced into the extension 5 of the cavity 6 in the manner described, it may be held in place by the screw pin 3 or in any other suitable manner.

In threading the shuttle, the weaver passes the filling first between the guard s and the wall 2", until the filling will be admitted to the slits q q. The filling is then entered into said slits, having first forced back the tension plate will extend between the same and the plate h. The filling is then looped under the tongue ;0 which on a View to Fig. 1 will be seen to stand clear of the walls of the extension 6 of the cavity 6. The free end of the filling, now looped under the tongue.

so that the filling and the wall of the shuttle in which the eyelet 7 is arranged, is then passed through the aperture t (made sufiiciently large for the purpose) and, having then been entered into the slit u, it will find its way into the filling-guiding eyelet Once in the eyelet f it is retained therein by the eyelet 0. It will be observed that the tongue 72 is sufficiently depressed so as to effectively sheath it against catching in the warp when the shuttle is in use. To facilitate looping the filling under the tongue the material of i the body of the shuttle around the extension 6 of the cavity 6 is'recessed as at 2.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a shuttle, a. filling-tension device inv clu'ding two. coacting filling-gripping members having relatively broad filling-grip-' ping faces bearing flatwise against each other and each extending substantially vertically, one of said 'meinbers being elastically held against the other and pivoted on a substantially horizontal axis below said gripping faces, the 'space formed between said members when the pivoted member is moved out of contact with the other member Copies of this patent may be obtained for five cents each, by addressing the having an unobstructed downwardly open entrance thereto whereby to admit the filling between said members by a downward movement thereof, substantially as described.

2. In a hand-threading shuttle, the combination of a shuttle body, a supporting part arranged therein and having spaced lateral projections formed with filling-guiding slits and also having a filling-holding tongue projecting toward one end of the shuttle body, means, carried by said part, for retaining the thread in said slits, and a spring actuated tension member arranged between said projections .and normally held in filling-gripping relation to said supporting part, said tension member being arranged substantially vertically, pivoted at or near its lower end and having its upper end-portion exposed for manual engage ment. a
